Internal Cable Rattle

I have a 2012 Carbon Cube GTC Pro and have had the Cube 'fix' by my LBS to resolve the internal cable rattle issue in the top tube. Problem is it hasn't worked / been fitted correctly and still rattles to the point of driving me mad.

Does anyone know of a aftermarket foam type product I could slip down the cable to sort it once and for all. It would need to have an internal bore the size of a brake cable sleeve and an external bore of less than about 5-6mm to fit through the cable exit hole in the top tube.

Any help would be much appreciated.

I have rhe same problem I just come to the fact I have to put up with it

I’m sure you should have a fasteners and fixings supplier near you that would be able to help with some kind of rubber grommets to space out along the cable housing to lessen it. Failing that get some rubber to drill and punch out your own. Hope that helps.

I've often wondered about internal routing and why it fell out of favour last time. Probably because of issues like this.

How many watts do you need to be putting out before the drag from an external cable becomes detrimental to any noticeable degree? Not trolling, genuinely interested to know if there is any evidence of the aero benefit for those with thighs slightly smaller than Cancellara or Hushovd.
